A severe case of iatrogenic botulism associated with COVID-19 infection.

Background: The botulinum toxin is an extremely potent substance that impacts the nervous system. There has been a rise in cases of medical poisoning associated with it, particularly in the field of plastic and aesthetic procedures, in recent years.

Case Description: A 51-year-old woman underwent a facial wrinkle reduction procedure with an unauthorized injection of 100 U of botulinum toxin at an unlicensed medical facility six days prior to hospitalization.

[Influence of high-voltage electrical burn on the rheological property of platelet and leukocyte in rats and the interventional effect of pentoxifylline].

Objective: To investigate the influence of high-voltage electrical burn (HEB) on the aggregation and adhesion of platelet and leukocyte in rats and the interventional effect of pentoxifylline (PTX).

Methods: One hundred and eighty SD rats were divided into control, electrical burn (EB), and pentoxifylline treatment (PT) groups according to the random number table, with 60 rats in each group. (1) Ten rats were taken from each group at 15 minutes before injury for the observation of the microcirculatory perfusion of chest skin with Laser Doppler Perfusion Imager (LDPI), and the number of leukocyte adherent to mesenteric venule with Bradford Variable Projection Microscope (BVPM).

[Clinical effect of the concentrated suture fixation method on skin transplantation in the jaw and neck region].

Objective: To observe the clinical effect of the concentrated suture fixation method on skin transplantation on deep burn wound or wound of cicatricial deformity after burn in the jaw and neck region.

Methods: One hundred and fourteen patients, hospitalized from April 2002 to December 2011, with deep burn or cicatricial deformity after burn in the jaw and neck region, were divided into packaging group and concentrated suture group according to the random number table. Each group had 57 patients including 48 cases with deep burn and 9 cases with cicatricial deformity.

[Influence of high-voltage electric burn on the microcirculation of heart in rabbit].

Objective: To study the influence of high-voltage electric burn on the microcirculation of heart in rabbit.

Methods: One-hundred and twenty New Zealand rabbits of clean grade were divided into control group (C) and electric burn group (EB) according to the random number table, with 60 rabbits in each group. Rabbits in EB group were subjected to high-voltage electric burn (the electrical current flow into the left foreleg at the lateral side of proximal end and out from the corresponding site of the right hind leg) with voltage regulator and experimental transformer.

[Rheological changes of leukocytes in mesentery capillary of rats with transcranial high-voltage electrical burn and the therapeutic effects of ulinastatin].

Objective: To study the influence of transcranial high-voltage electrical burn (HEB) on rheological changes of leukocytes in mesentery capillary in rats and the therapeutic effects of ulinastatin.

Methods: Forty-five SD rats were divided into control (C), electrical burns (EB), and ulinastatin treatment (UT) groups according to the random number table, with 15 rats in each group. Model of HEB was reproduced in rats of EB and UT groups with voltage regulator and experimental transformer, and then rats in EB group was intraperitoneally injected with 2 mL isotonic saline while rats in UT group was intraperitoneally injected with 2 mL ulinastatin (2 x 10(4) U/kg).

[Alteration in bulbar conjunctiva microcirculation and interventional effect of Pentoxifylline after high-voltage electrical burn in rabbits].

Objective: To study the changes in bulbar conjunctiva microcirculation (BCM) and the therapeutic effect of Pentoxifylline on BCM disturbance after high-voltage electrical burn (HEB) in rabbits.

Methods: Forty-five rabbits were divided into control group (C), electrical burn group (EB), and Pentoxifylline treatment group (PT) according to random number table, with 15 rabbits in each group. Model of HEB was reproduced in rabbits from EB and PT groups with voltage regulator and experimental transformer.

Nup88 expression in normal mucosa, adenoma, primary adenocarcinoma and lymph node metastasis in the colorectum.

Objectives: It was the aim of this study to investigate Nup88 expression in normal colorectal mucosa, adenoma, adenocarcinoma and lymph node metastasis, as well as the relationship between Nup88 expression and clinicopathological features.

Methods: Nup88 expression was examined by immunohistochemistry in 84 normal mucosa samples, 32 adenomas, 181 primary adenocarcinomas, and 18 lymph node metastases from colorectal tumour patients.

Results: Nup88 expression was observed in normal epithelial and tumour cells.
